STOVE DAMPER.

Specification of Letters Patent.

Patented J an. 3, 1922.

Application filed February 3, 1921. Serial No. 442,155.

To all whom it may concern:

Be it known that I, ALoNzo CQNNELLY, a citizen of the United States,residin at T0- peka, in the countyof Shawnee and tate of Kansas, haveinvented certain new and use ful Improvements in Stove Dampers, of whichthe following is a specification, reference being had therein to theaccompanying drawings. 7

This invention relates to improvements in dampers, and particularly to adamper to be used in the pipe leading from a stove to a flue.

The object of the invention is the construction of a simple andefficient damper which will retard the escapement of heat from a stoveand yet will allow the obnoxious gases or fumes to readily escape tothe'outer atmosphere.

With this and other objects in view, my

invention comprises certain novel combinations, constructions andarrangements of parts as will be hereinafter described, illustrated inthe accompanying drawing, and more particularly pointed out in theappended claim.

In the drawing Figure 1 is a view of a stove to which is attached a pipeleading to a fiue, the pipe being broken away, showing my improveddamper therein in elevation.

Figure 2 is a vertical, sectional view of my damper.

Figure 3 is a plan view of the ring of the damper.

Referring to the drawing by numerals, l designates the stove, 2 thepipe, and 3 designates the flue. In the pipe 2 is positioned the damper4.

The damper 4: comprises an annular ring 5, provided with penetratingspurs 6; these spurs 6 are adapted to be forced through the walls of thepipe 2 to retain the damper in position within the pipe. Secured to theunder face of ring 5 is the retarding cone-drum 7 Positioned above thering 5 is an apertured cone 8, which cone 8 is provided with an annularflange 9; the flange 9 engaging the upper face of ring 5, therebyaffording an efficient bearing, enabling the cone to rest upon the ring5.

The suction or draft through a the apertured cone 8 is suflicient todraw the burned gases or fumes through the damper, yet the heat unitswill be retarded considerably by striking against retarding cone-drum 7and the apertured cone 8, heating the damper and thence heating the pipeto a greater degree because the metal damper and pipe will give off theheat to a greater extent than would be the case if the pipe was leftfree by reason of no damper being the-rein.

While I have described the preferred embodiment of my invention, andhave illus trated the same in the accompanying drawing, certain minorchanges or alterations may appear to one skilled in the art to whichthis invention relates, during the extensive manufacture of the same andI, therefore, reserve the right to make such alterations or changes as.shall fairly fall within the scope of the appended claim.

What I claim is:

As a new article of manufacture, a damper ALONZO CONNELLY.
